Programmatically list all variables of a NetCDF file using netCDF4 and Python

Question

How do I programmatically list all variables of a NetCDF file that I have read in using netCDF4 and Python?

import netCDF4
dset = netCDF4.Dataset('test.nc')

Solution 1

From the documentation, here, it looks like it would just be:

import netCDF4
dset = netCDF4.Dataset('test.nc')
dset.variables

Solution 2

dset.variables.keys() 

would provide you with a list of the variables.

Solution 3

To list all variable names as strings just do:

list(dset.variables.keys())

or simple

list(dset.variables)
